Oceans

Front

What direction do ocean waves move?

Back

Ocean waves move in a circular motion.

Front

What causes the Coriolis Effect?

Back

The Coriolis Effect is caused by Earth rotating on its axis.

Front

Where do cold ocean currents generally come from?

Back

Cold ocean currents generally come from both the North Pole and the South Pole.

Front

Why is the ocean salty?

Back

The ocean is salty because rivers and streams carry salty minerals from inland to the ocean.

Front

Where do warm ocean currents generally come from?

Back

Warm ocean currents generally come from the Equator.

Front

What is the main reason for ocean currents?

Back

Ocean currents are primarily driven by wind, the Earth's rotation, and differences in water density.

Front

Define oceanic circulation.

Back

Oceanic circulation refers to the large-scale movement of water in the world's oceans, driven by factors such as wind, temperature, and salinity.

Front

What is the role of the sun in ocean currents?

Back

The sun heats the ocean surface, creating temperature gradients that drive convection currents.

Front

What are gyres?

Back

Gyres are large systems of circulating ocean currents, typically driven by wind patterns and the Coriolis Effect.

Front

Explain the difference between surface currents and deep ocean currents.

Back

Surface currents are driven by wind and affect the upper layer of the ocean, while deep ocean currents are driven by differences in water density and temperature.
